The exFAT partition should be recognized by Windows in any case, so the only thing I can think of is that you're using it over firewire and the Windows drivers don't feel like playing nice. In either case, I suggest using the OSX disk utility under applications -> utilities, select the root of the drive in the left pane, and format the whole drive as exFAT under the "erase" tab. There's no real reason to use a hybrid partition setup on an external drive because both OSes can read and write exFAT natively.

Hello brother i had 2 the same problem before but i ha managed it , first you can backup all the from the hard drive and re partion it from disk utility on mac and be sure the format is with the MS-DOS , it will be fine and the problem will be solved...
All the best...

Are there any disadvantages to doing it this way? Will time machine still work? Also I did try it over both, firewire and USB 2.0 - and I didn't see a single mounted partition either time

the DOS format will not help me here :/ please figure out what you're talking about before posting.

I've had a bit of trouble with exFAT drives formatted in OS X showing up in Windows as well. I would try formatting the partition to FAT32 in OS X, then format it back to exFAT in Windows - this is what I've done with all my drives and haven't had any problems since.

Ah, I had forgotten about Time Machine because I don't actually use it myself. Well, I should have asked to begin with, does the drive show up at all in Windows Disk Management (search for "computer management" under the start menu)? Even if it can't see any partitions, it should be able to see the physical hard drive, at which point you may as well just use Windoze to format it exFAT, and then partition enough drive space in Disk Utility under OSX for Time Machine, which shouldn't be a problem at all because you have 2TB to work with.
